SPECIFICATION forming part of Letters Patent No. 290,071, datedDeceinber 11, 1883. Application filed August 24, 1883. (No model.)

To a/ZZ whom it may concern:

Be it known that I, TOLBERT LANsTON, a citizen of the United States,residing at Washington, in the District of Columbia, have in-` ventedcertain new and useful Improvements in Window-sashes, and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable Others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, andto letters or figures of reference "markedthereon,.which form a part of this specification.

Figurel of the drawings is a representation of an elevation of theinside of the window. Fig. 2 is a horizontal section through thewindow-frame and strips, showing the tops of the sashes. Fig. 3V is avertical section through the window, top strips, sashes, and sill. Fig.4. is a sectional detail, spring-bolts in the slots of the verticalrails. Fig. 5 is a sectional view of a modification ofthe guide-strips.Fig. 6 is a view of the blank `V-notched to form the side and bottomrails Of the sashes, Fig. 7 is a cross-seotion of the blank rolled butnot V-notched, from which all except the middle rails are formed. Fig.8is a cross-section of these rails formed from the blank and packed-withthe wood and rubber strips. Fig. 9 is the same with a packing ofcomposition instead of the strip-rubber. Fig. l0 is the Hshaped rolledblank, from which the middle rails,v shown packed in cross-section inFig. 11, areA formed'. Fig. 12 is a sectional detail view ofone of outerstrips x, and Fig. 13 is a perspective detail view of one of thecornerpieces. Y

This invention has relation topnietal window.`

sashes for receiving removable glass panes and removable screen-sheets;and it consists in the construction and novel arrangement of devices, as-will be hereinafter fully described,

' and particularly pointed out in the claims'appended.

Referring by letter to the accompanying drawings, A designates thewindow-frame, which is of the ordinary construction, except that theboxes for the weights are not formed therein in the usual manner, butare formed as will be hereinafter explained.

Theframes ofthe sashes are formed of metal, wood, and rubber packing, orgypsum, or

as shown in the drawings.

lother composite .matter of a consistency that ,will admit of its beingpoured into a former or mold, orv into the sash itself, the glass beingvfirst placed therein. The metal portions of the outer vertical railsandthe transverse side rails and bottom rails of the sash-frames,

isflrst rolled in T form in cross-section, the stem c of the T beinggrooved longitudinally, The cross-arms d d ofthe T are then curvedupwardly and inwardly above the stem c until their edges nearly meet.This manipulation forms ahollow railpiece, e, having a continuous doubleflange, e', on one side thereof. What may be termed the bore of therail-strip is then fprovided with a wooden and rubber or metal andrubber packing, to form the seat for the .edges of the glass frame orsheet-screen, as the case may be.

The wooden packing is preferably composed of a half-Oval strip, f, andtwo fiat strips, g g,

at rightl angles to the fiat face of the strip f,

and resting against it, theadjacent cornersof the strips g g beingrounded and less than the pane-spaces being left between them. Betweenthe metal and the wooden strips, but

lnot in the pane-space h, rubber packing is interposed, it beingcemented or glued to strips g g. The rubber packing is to be of suchsize as will bring the wooden strips g g nearly together,-or at adistance apart less than the thickness of` the glass, so that when thelatter is inserted'it will be gripped by and held rmly between thestrips g g, and compressing the rubber and tightening the packing. Imay, however, use gypsum or other composite matter and pour it .into thespaces occupied by the rubber for the same purpose-viz., to preventrattling, to serve as a weather-strip to prevent the entrance of rain orcold air,

and to prevent the glass from being broken by jars in raising andlowering the sashes, and also to permit the removal of the glass panefor the purposes ofwashing it, or forthe substitution of thescreen-sheets in warm weather. The middle vertical. rails of the sashesare packed similarly to the strip just IOO 2 :sacem described, omitting,however, the half-oval strip f; but the manner of packing the strips maybe varied without departing from the character of the invention, theessential feature of which, in this particular, is to form the bearingfor the edges of the glass pane or screen-sheet, as the case may be. Themiddle rails, 7.1, are, however, slightly dil'i'erent in constructionfrom the side and bottom rails. They are iirst rolled `in -l shape, andthe sides ZZ are curved inwardly on opposite sides of thewcb 1a oi" theH until they nearly meet, the space being for the edges of the glasspane or screen-sheet, as the ease may be.

The horizontal top rails may be and are formed from the same strip asthe side rails and bottom rails, but they are cut oil" at the V-notches,and are secured to the upper ends of the vertical side rails and middlerails by sliding latches p in the groove of said top rails, q, whichlatches engage lateral slots r in the upper ends of the webs of thevertical rails, as shown. The top rails, (l, are thus made removable, inorder that the glass panes and screen-sheets may be removed and replacedat will. The screen -sheets are of wire-gauze bound at the edges by ametal frame, as shown.

The ways in which the sashes slide are also of metal. The middle strips,a, with which the sides and top ol the window-frame are provided, have arectangular central projection, c, and lateral flanges v v, i'ormed byrolling a ilat strip of metal into such shape, and the groove formed inthe strip lits overa rectangular strip, ci, secured to the window-frameat the longitudinal middle line ot' the inner faces of the sides and topof the same, and held in place by screws.

Instead of making the middle metal strip in one piece, the rectangularwooden strip al may be made smaller in cross-section, so that the innertransverse face may come nearly rlush with the edges of the shorterllanges of the side strips, yw fw, the distance from said edges be` ingsuilicient to place a ilat strip, e, upon the face of wooden strip etand secure it in place by screws. The projection o in this instance isrolled separately from a single dat strip, and is secured upon the ilatstrip e by screws passed through the projection, and also through theilat strip t, into the wooden strip ci, when reduced in size incrosssection. The inside and outside strips, 'w lw', are similar inconstruction, except that the top strips are shorter than the sidestrips. These are also of metal, and are rolled in rectangular form incross-section, so as to have side flanges, .fr a, the iianges av beingshorter than the llanges as, and resting,when in place,against the facesoi the lateral flanges o Uof the middle strips. The iianges m havelateral danges a extending outwardly from them at right angles thereto,and these iianges .r2 are provided with elongated screw holes or slotsy, through which the securing-screws are passed into the windowframe tosecure the strips fw w in place. The

slots y enable me to adjust the inside strips, w, to or from the slidingsashes. The outside strips, yw, have similar screw-holes, as it isnecessary to adjust them also. By this construction of grooved ways, theweight-boxes are formed on cach side oi' the central wooden strips andare separately boxed, avoiding danger ol' wedging in passing, and aredirectly behind the grooves. The miter ends of the strips yw a do notquite meet, a imiter-space, s, being left between them. Angularcornerpieces c', however, are employed to close these spaces and lockthe j oints at these points, and said corner-pieces c enter the smallerpoints of these spaces and extend over the remainder oi' the spaces andlap the faces of the strips. The corner pieces z have angular Vllanges@and are secured to the window-frame by screws, as shown. The strips w ware removable, as are also the corner-pieces, and the sashes may beremoved at any time to repair the weights. The pulleys over which thecords run are secured to the rear faces of the Vlianges of the middlemetal strips near or at the upper ends of the same. The sill-plate y isalso of metal, and is secured in place by screws and the corner-piecesz. The lower rail ot' the top sash has a lateral longitudinal horizontalilange, a', on its inner face, and the top rail of the lower sash has asimilar iiange, on its outer face. These tianges a a2 meet when thesashes are closed and exclude wind,

ytiter, dust, and cold air.

The middle rail of the upper sash is provided near its lower end, on theinner side,with a iingerpicee, c, by which said upper sash ismanipulated.

The metal portions of the sashes, strips, corner-pieces, and sill-platemay be nickelplated or otherwise plated and ornamented to suit the tasteof the purchaser; or the metal may be painted over the exposed parts, ifdesircd.

There is very little friction created in sliding the sashcs, on accountof the smoothness and material of the rails and ways. There is butlittle trouble attending the cleaning of the windows, and they are verydurable and decidedly ornamental and comparatively light.

The corner-pieces permit side strips, w and w', that are not evenlymatched to be used.

The rail-pieces, being rolled and bent as described, may be made quitecheaply.

Having thus fully described my invention, what l claim as new, anddesire to secure by Letters Patent, is-

1. A sash-frame having its side rails and bottom rail made of one pieceof rolled metal provided with suitable packing, substantially asspecihed.

2. A saslrhfame having its side and bottoni rails made of one piece ofmetal rolled into shape and V -notched at the miter-corners and packed,as described, in combination with a removable rolledfmetal top rail,substantially as speciiied.

IOO

IIO

vertical rail rolled in H form, and then having its wings bent or curvedinwardly on opposite sides of the web of the H, substantially asspecied.

5. A rolled-metal side, top, or bottom rail, rolled in T form, andhaving the wings of the T curved upwardly and inwardly above the stem,and the stem longitudinally grooved to form a double iiange,substantially as specied.

6. In a window, the combination, with the rolled-metal middle stripssecured to the central wooden strips, of the inner and outer wayl stripsof rolled metal, having their shorter iianges bearing against theiianges of the middle strip, and their slotted flanges secured to thewindow-frame by screws, substantially as specied. l

7. The combination, with the inner and outer way-strips, the middlestrips, and the sashframes, of the removable corner-pieces covering andengaging the miter-spaces, substantially as specified.

8. In a window, the weight-boxes formed by the combination of therolled-metal middle strips secured to the wooden central strip and theinner and outer rolled-metal side strips secured to the window-frame,substantially as specied.

In testimony whereof I affix my signature in presence of two witnesses.
